Servicing and inspections


The best way to make sure your boiler is working its best all year round is a yearly servicing and inspection by a trained expert. Not only is this a great way of avoiding any problems it can also help make sure you’re using your boiler in the most efficient way. This saves you fuel and lowers your carbon footprint.

Booking a service is simple. It can be arranged by email or by phone in a matter of minutes and it’s even possible to arrange a yearly reminder so that you don’t have to worry about missing out next year. Our fully qualified engineer will make sure your heating system is working perfectly and if anything needs repairing they can talk you through the options before the problem becomes any worse. Many repairs can even be performed right there and then, saving you from having to spend any more time waiting for your boiler to be back in perfect working order.

Annual Servicing


Having a yearly boiler service is the best way to keep your heating working its best. In fact, a WHICH survey in 2020 found that over 70% of boilers serviced every year never needed a repair. The small yearly cost of an inspection could end up saving you a lot of money down the road. IT also helps you live safe in the knowledge that your boiler is working fine and not hiding any little issues that will only get worse and worse as time goes on.

The engineer should then provide a service report detailing all the checks they’ve performed and giving the all-clear or listing any issues they recommend you look into. They can talk you through any questions you may have and advise on anything you should consider having repaired or replaced.

Our annual service includes all the following checks:

  • A visual inspection of the boiler
  • Internal and external flue inspection
  • Pressure check
  • Safety system checks
  • inspection of the seals and pipes
  • Internal inspection (with casing removed)
  • Cleaning of required components

Most of our inspections take around an hour and involve removing the boiler covering for a thorough inspection.

At the end, you’ll receive a fully completed written report. If you have any concerns this is a good time to ask any questions and well be sure to talk you through it.

New boiler installation

If your boiler is over 10 years old the inspection is likely to take a bit longer. Your engineer may suggest upgrading to a newer model if repairs and new parts would be uneconomical.

Choosing a new boiler is a big decision. Whether you are replacing an old, tired boiler or fitting a brand new heating system to a new property we can help. There are times when fixing an existing system is no longer economical. While it may seem expensive, it can end up saving you a lot of money in the long run.

There are many reasons to get a new boiler, including:

  • Lower energy bills
  • Lower carbon footprint
  • Better control over your heating system
  • Safer and more reliable than older systems
  • Peace of mind whatever the weather

There are a lot of options to choose from and picking the right one is essential. A boiler that’s not powerful enough will leave you shivering through cold winters, while one that’s built for bigger spaces can be unnecessarily expensive. An experienced heating engineer can help you choose just the right model for your needs. Choose from a range of top models from (Worcester Bosch, Baxi, Potterton) and more.
